How safe is the dealer with your stuff?

Not an RV, but we had a car in for service once, that was stolen out of the dealers "secure" back lot. It was found one morning by the police burning behind a discount store. Reason it was at the dealer's was for, it was running about a mile and shutting down, the store was a mile away from the dealer. Dealer didn't know it was gone when called after being contacted by her the next day, 12 hours after we were contacted by the police 24 hours after it was found. She was told "it would be done tomorrow." She advised of theft. Dealer said "turn it in to your insurance", we said "no". 3 months later, the day after our attorney contacted the owner of the dealership with his intention to go to jury trail and would be subpoenaing the records of purchase and selling prices of all used cars for the months since ours had been stolen, by his dealership. The dealer sent us a check for the purchase price from a year before and our attorney's time, that day.
